Ibhethri le-Graphite elicwebezelayoidlala indima ebalulekile kubuchwepheshe bebhethri besimanje, ikakhulukazi kumabhethri okugeleza kanye namaseli kaphethiloli. Njengento ephumelelayo nehlala isikhathi eside, i-graphite felt inikeza ukuhanjiswa kukagesi okuhle kakhulu kanye nokuzinza kokushisa, kuyilapho futhi inegalelo ekusebenzeni kwebhethri okuthuthukisiwe, isikhathi eside sokuphila, kanye nokuphepha okuthuthukisiwe. Ekusetshenzisweni kwamabhethri okugeleza kanye namaseli kaphethiloli, izakhiwo ezihlukile ze-graphite better felt ziyenza ibe yingxenye ebalulekile kulezi zinhlelo zokugcina amandla ezisebenza kahle kakhulu.
Ukusetshenziswa kwe-Graphite Battery Felt kuma-Flow Batteries
Amabhethri okugeleza, ikakhulukazi amabhethri okugeleza e-vanadium redox (VRFB) kanye namabhethri okugeleza e-zinc-bromine, acwaningwa kabanzi futhi asetshenziswa kubuchwepheshe bokugcina amandla. Agcina futhi akhiphe amandla ngezinto ezisebenzayo ezincibilikisiwe ku-electrolyte, eziwanika isikhathi eside sokuphila kanye namandla amakhulu okugcina amandla uma kuqhathaniswa namabhethri endabuko. Ekwakhiweni kwala mabhethri, i-graphite battery felt ivame ukusetshenziswa ezingxenyeni ze-electrode, ikakhulukazi lapho i-electrolyte egelezayo ixhumana nezinto ze-electrode.
Ukuqhuba okuphezulu kwe-graphite felt kuyinzuzo eyinhloko ekusetshenzisweni kwayo kumabhethri okugeleza. Kumabhethri okugeleza, ukusabela kwe-electrochemical kwenzeka phakathi kwe-electrolyte nama-electrode, ngakho-ke ukuqhubela phambili kwama-electrode kubalulekile ekusebenzeni kwebhethri. Njengezinto ze-electrode, i-graphite felt ingakhuthaza ngempumelelo ukunyakaza kwama-ion ku-electrolyte futhi iqinisekise ukudluliselwa kwama-electron okuphumelelayo, okuthuthukisa ukusebenza kahle kokushaja kwebhethri kanye nokukhipha.
Ngaphezu kwalokho, i-graphite felt idlala indima ebalulekile ekuphathweni kokushisa ngaphakathi kwamabhethri okugeleza. Ngesikhathi sokusebenza kwamabhethri okugeleza, kukhiqizwa ukushisa kwangaphakathi. Ukushisa okuhle kakhulu kwe-graphite felt kusiza ukuqeda lokhu kushisa, kuvimbele ibhethri ekushiseni ngokweqile futhi kuqinisekise ukuthi isebenza ngaphakathi kwebanga lokushisa elifanele. Leli khono lokuphatha ukushisa alisizi nje kuphela ukwandisa isikhathi sokuphila kwebhethri kodwa futhi lithuthukisa ukuphepha kwalo, kunciphisa ingozi yokwehluleka kwebhethri ngenxa yokushisa ngokweqile.
Ukusetshenziswa kwe-Graphite Battery Felt kuma-Fuel Cells
Amaseli kaphethiloli amadivayisi aguqula ngqo amandla amakhemikhali abe amandla kagesi ngokusebenzisa ukusabela kwe-electrochemical, okusetshenziswa kabanzi ezimotweni zikagesi, izinsiza zamandla ezisekelayo, kanye nezinhlelo zamandla avuselelekayo. Ukusetshenziswa kwebhethri le-graphite elizwakala kumaseli kaphethiloli kuncike kakhulu endimeni yalo njengengqimba yokusabalalisa igesi (i-GDL) kanye nezinto ze-electrode. Ukubaluleka kwalo kubonakala kakhulu kumaseli kaphethiloli we-proton exchange membrane (i-PEMFC).
Kumaseli kaphethiloli, i-graphite felt isebenza njengengqimba yokusabalala kwegesi (i-GDL), enesibopho sokusabalalisa ngokulinganayo amagesi asabelayo njenge-hydrogen ne-oxygen ezindaweni ze-electrode, kuyilapho isebenza njengendawo yokuhambisa umoya. Ngenxa yokuhambisa umoya okuhle kakhulu, i-graphite felt ingadlulisela ngempumelelo ama-electron akhiqizwe ngaphakathi kweseli aye kwisekethe yangaphandle, okwenza kube nokukhishwa kwamandla kagesi. Isakhiwo sayo esinezimbobo senza kube lula ukusabalala kwegesi kanye nokuqhutshwa kwe-electrolyte, okuqinisekisa ukuthi ukusabela kwe-electrochemical kumaseli kaphethiloli kuqhubeka kahle.
I-graphite ezwakala kumaseli kaphethiloli ayidingi nje kuphela ukunikeza ugesi omuhle, kodwa futhi kumele ibe nokumelana okuhle nokugqwala kanye nokusebenza kahle kokushisa okuphezulu. Njengoba amaseli kaphethiloli esebenza ezindaweni ezinokushisa okuphezulu kanye nokugqwala, ukuzinza kwamakhemikhali kanye nokuzinza kokushisa kwe-graphite felt kwenza kube ukukhetha okuhle kakhulu. Ingasebenza ngokuzinzile ezimweni ezimbi kakhulu isikhathi eside, igweme ukuwohloka kokusebenza ngenxa yokuguga kwezinto noma ukugqwala.
Ngaphezu kwalokho, i-graphite ezwakala kumaseli kaphethiloli nayo iyasiza ekwenzeni ngcono ukusebenza kahle kokusabela ngesakhiwo sayo esiklanywe kahle. Ukuhlelwa kanye nokubekwa kwezingqimba ze-graphite akugcini nje ngokuthuthukisa amandla ayo okusebenza kodwa futhi kuthuthukisa ukusebenza kahle kokugeleza kwegesi. Ngokulungisa ngokunembile i-porosity kanye nesimo sesakhiwo se-graphite felt, amandla okukhipha kanye nokusebenza kwamaseli kaphethiloli kungathuthukiswa kakhulu.
Ukuthuthukiswa Kwesikhathi Esizayo Kwe-Graphite Battery Felt
Njengoba ubuchwepheshe bebhethri lokugeleza kanye namaseli kaphethiloli buqhubeka nokukhula, amathuba okusetshenziswa kwe-felt yebhethri le-graphite ayanda. Abacwaningi bahlola izindlela zokuthuthukisa ukusebenza kwe-felt yebhethri le-graphite ngokusebenzisa izinhlanganisela ze-graphite, amasu okusebenzisa izidakamizwa, kanye nokwelashwa kwendawo. Isibonelo, ukuthuthukisa ukwakheka kwesakhiwo se-felt yebhethri le-graphite kungandisa ukuhanjiswa kwayo, kuthuthukise ukumelana kwayo nokugqwala, futhi kuthuthukise amakhono okuphatha ukushisa. Lokhu kuthuthukiswa kuzothuthukisa ukusetshenziswa kwamabhethri okugeleza kanye namaseli kaphethiloli ezindaweni zokugcina amandla nokusebenza okuphezulu kanye nezinkambu zokuguqula.
Ekuphetheni, ukusetshenziswa kwebhethri le-graphite elizwakalayo kumabhethri okugeleza kanye namaseli kaphethiloli, kanye nokuqhuba kwayo okuhle kakhulu, amakhono okuphatha ukushisa, kanye nokuzinza kwesakhiwo, sekuyinto ebalulekile yalezi zinhlelo zokugcina amandla ezithuthukisiwe kanye nokuguqulwa. Njengoba ubuchwepheshe bamandla buqhubeka nokuthuthuka, ibhethri le-graphite elizwakalayo lizodlala indima ebaluleke kakhulu ekushayeleni ubuchwepheshe bebhethri obusha, ukuthuthukisa ukusebenza kahle kwamandla, kanye nokuthuthukisa intuthuko esimeme.
